Windows 7: Where is my free space?

Where is my free space?


I have a 60gb OCZ ssd, so space is at a premium. I did disable hibernation for starters which helped.

If I go to Windows Explorer & right click on my drive, it says I am using 42.3GB with 17.1GB free. If I go into my C drive & select all & then right click & goto properties, it says I am using 32.8 GB & that is also the size on the disk.

Where is my missing 10 GB?

I do have hidden files being displayed if that matters.

There's a free program called WinDirStat that will show you exactly where and what is using your space.

Can you make a different selection say 1 or 2 folders so your size would be less than 32G and see if it gives you a different number for the Size on disk?

the 10G might be allocated for the SSD for file table? swap? I have heard there is space used, but not remembering what it was for.

I've had a look at mine, and found the same situation. My figures, in the same order as yours, are as follows:

Just to confuse things, and make it a bit more perplexing, TreeSize Free (JAM Software - Windows Freeware) gives the following result:

This is what WinDirStat ( says (note that I have installed this program AFTER the above images were taken):

System Restore points normally use about 15% of the disk space.

Hrmm, it looks like I have system restore turned off already. I did check just a few folders & it does show less than 32gb.

Any other ideas on where to look?

Thanks for all the replies!

It's most likely the system restore taking up the space.

Right click My Computer, Properties
Click Advanced System Protection
Click System Protection Tab
Click on C drive and choose Configure button.

It will then show you the current usage and how much could be used.
